BOILER-FLUE CLEANER.

Application filed November 18, 1908.

Specification of Letters Patent.

Be it known that l, JAuns .l. l m'xx, a

citizen oi the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have lnVPHlQll cm'tanrnow and useful lmprovemeius in Boiler-Flue Clean ers; and I do hereby declare the following to be a full, clear, and c: act description of the invention, suchns will enable others skilled in the art to which it appcrtains to make and use the same. This invention relates to improvenuuits in boiler flue cleaners, and has for an object the provision of improved means which may be readily applied to any class of boiler for forcing steam through the hues of the boiler.

Another object in view is the provision oi means readily secured to a boiler arranged for injecting a steam blast into the hues of the boiler forcleaning the same without necessitating the drawing of the lire or reducing the steam pressure. 7

A further object of the invention is the arrangement of a tube through which a blast of steam is ad apt-ed to pass for blowing out each ot-the lines of; a boiler independently, the tube being moved from one line to the other during the process of" cleaning so as to permit an individual cleaning of each flue.

With these; and other objects in view the invention comprises certain novel construe 'tions, combinations and arrangcn'ient of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure l is a fragmentary View of an engine with the invention applied thereto, parts being broken away to better disclose the invention. Fig. 2 is an end view of the structure sbownin Fig. 1. Fig. 3 is a section through a battle and so )porting plate.

In t 0 construction of cleaners for lines of boilers-variohs means have been arranged either for cleaning the tines in groups or all at once, but in such devices there is more or less reduction of steam pressure in the boiler during the operation of the cleaning device,

either by reason of the dying down of the fire or by reason of the openingot' the fire chamber for the insertion of the cleaning device. In some instances the cleaning devices are arranged at the front end of the boiler and when the cleaning blast is forced into the tines the same must act against the fire draft which injures the effect of the pipe engage lines 1 Patented March 9, 1909.

, upon the boiler, and consequently greatly reduces the steam.

in the present invention the above objeotionable features are aimed to be overcome and yet to thoroughly clean the various lines of the boiler, which may be of any desired construction, and without appre- .ciabl v diminishing the steam pressure or appreciably affecting the burning of the iirc. in the accompanying drawings is shown one embodiment of the invention in which 1 indicates a steam boiler of any desired type, either locomotive or stationary type. Formed in the boiler at the end in which the the chamber 2 is located is an opening 3 into which is fitted a baiiiing and supporting plate 4 which is formed with an aperture 5 that is constructed oi a conical shape on each side tapering to the center. A tube 6 is. fitted into the battling or supporting plate 4 which, together with the plate 4, substantially fills opening 3, but by the construction of opening 5 tube 6 may be moved longitudinally or pivoted in any desired direction in order to have the end thereof of the boiler l. Secured to the outer end of tube 6 is a flexible pipe 8 that in turn is connected with a steam carrying pipe 9 having a regulating valve 10 which regulates the steam pressure that is admitted to tube or blast pipe 6. Pipe 9 is preferably connected to a steam dome 11 in order to secure substantially dry steam.

In 0 )eration when it is desired to clean the lines ot a boiler all that is necessary is to apply the flexible tube 8 to pipe 9 and insert tube 6 into one of the lines 7, and then turn the steam on at valve 10, valve 12 having previously been turned on. The steam will then be forced thyough one of the fines 7 until the same has been sulliciently cleaned and then the operator will move tube 6 until the end engages another hie 7 and holds the same in that position until the second line has been cleaned. The tube 6 is then moved from the second lluc to the remaining ilues in succession until all of the lines have been thoroughly cleaned, the opening 5 permitting sullicient movement of tube 6 for this purpose, and yet, by reason of the construction of the opening in plate 4, substantially no heat is lost through opening 3. By cleaning the fines in this manner it Will be observed that only one fine is cleaned at a time and the remaining fines may act in the usual manner for the passage of the products of c0mbusexpense, though sirable as the same permits a free movement of pipe 6 and may be readily renewed at small the system .of pipes is used the same must be arranged with proper pivotal joints for permitting any desired reciprocatory or pivotal or other movement of pipe 6 as might be desired, and in addition usually there is applied a ball and socket joint where the pipe 6 eng-a es the system of pipes. a

, flhe device has been shown in connection with an ordinar boiler of the locomotive type, but it wil be evident that the same may be used with any other kind of boiler to equal advantage. Also if desired the late 4 could be made sufficiently large to t into door-way 3 in order to obviate the necessity v of constructing. an auxiliary openin 3.

When theplate 4 is maddsufiiciently arge for fitting into door-wa 3 the door vof doorway 3 is simplyopen'e and the plate inserted, together with pipe 6, and the operation is performed in the *psual manner as above set orth. What I claim is: i

1. In a boiler flue cleaner, the combination with a boiler having an opening formed in one end thereof, a tube adapted to be projected through the opening and to engage successively the flues in said boiler, a baflie plate formed with means'for permitting a univerif desirable a system of pipes could be used in place thereof. When sal movement of said tube, and flexible means connected with a supply of gaseous pressure.

2. In a boiler flue cleaner, the combination with a boiler havin an opening formed in he end in which the flre chamber is located, a

baffling plate arranged with a double beveled aperture assin therethrough, a tube passing throug isai aperture in said plate and by the construction of said aperture being permitted a free movement thereof for permitting the insertion of the endof the tube into the flues of the boiler, and flexible ,means connected with. said tube and with said boiler for conveying steam to said tube whereb a-steam blast is'admitted to said flues w on the end of said tube islplac'ed therein.

3. In a boiler flue cleaner, the combination with a boiler formed with a passage way in the end in which the fire chamber is located, a baffle and supportin plate positioned in said passage way and ormed with an aperture passing tl erethrough, said a erture being formed with conical shaped wa ls merging in the center of the plate, a'tube assing throu h said aperture and en'gagingt e flues of sai boiler, said aperture permitting'suflicient movement of said tube for permitting thevin'sertion of the end of the tube into the ends of any ofsa'id flues, a fleirible hose connected to said tube and to said boiler, and

means for regulatin the amount of steam Y pagsing through -sai flexible hoseand'said tu en In testimony whereof I aflix my signature in. presence of two witnesses. Y
